SEALIEN - ROV-based Trencher

Sealien's ROV-based trencher is purpose-built landing cable and pipeline operations in dynamic subsea environments. Its streamlined buoyancy design minimizes hydrodynamic resistance, while the suspension-integrated track system ensures stable movement across uneven seabeds. The modular platform allows for versatile customization, and a higher ratio of self-developed components enables taster supply and easier servicing. Equipped with a proprietary cable tracking system, the trencher supports efficient multi-sensor deployment, real-time burial depth monitoring, and automated post-inspection reporting. Intelligent control software, powered by machine learning, dynamically adjusts vehicle posture, jetting pressure, and flow to match varying soil conditions, ensuring precise, high-quality burial for a wide range of cables and pipelines.
